Specification of Letters Patent.

Patented April 9, 1907.

Application led December 4,1906. Serial No. 346,328.

To aZZ whom it may concern:

Beit known that I, JAMES M. RUDE, a citizen of the United States,residing at Covington, inthe county of Kenton and State of Kentucky,have lnvented certain new and useful Improvements in Metal Laths, ofwhich the following is a specification.

\ My invention relates to sheet-metal lath' fully set forth in thedescription of the accompanyi'ng drawings, forming a part of this`speclfication, in which- Figure 1 is a pers ective view of a sheet ofmy improved met' lath. Fig. 2 is a crosssection through a columnillustrating the lath in position for use. Fig; 3 is an enlarged endview' illustrating the mannerof connectin twoends of the lath. Fig. i isan enlarge end view of a modified form.

1 represents the ,metal lath, which is formed with the orifices 2, therebeing a series of parallel dovetails or corrugated ribs 3 at suitableintervals. In a iven lath these dovetalls are of alternately differentsizes, so

thatone may be fitted into the other, as indicated in Fig. 3, tointerlockthe opposite ends of the lathing together or to interlock twosections of lath together.

In Fig. 2, 5 represents the upright I-beam, which is surroundedv by theconcrete 4. The lath is bent into circular form and placed around theI-beam, the concrete being filled in and compactly crowded into theanglenotches formed by the ribs 3. At the same time the concrete willtake into the orifices 2 and make a very solid structure. The other sideof the lath, with its orifices and the grooves 6 formed by the corruated ribs, also forms a suitable retaining-sur ace 'for the plaster.This makes a very strong structure with particularly desirable concreteand plaster holding formation.

Having described my invention, I claim- A metal lath formed ofperforated sheet metal, having a series of dovetail ribs formed atsuitable intervals resentin taining and plaster-ho ding surfgacesonoppoconcrete-re? site sides of the lath, the successive doyetails beingalternately differentiated in "size whereby a larger rib could beinterlocked with a smaller, substantially as described.

In testimony whereof I have hereunto set my hand.
